You could listen to the touch event and make sure event.action is TouchAction.up.

Edit: If you want to attach your own implementation of UIScrollViewDelegate on iOS, you could do this. My version of delegate accepts the original delegate as a parameter, so I don't loose anything that is already implemented in the original delegate.

(<any>ScrollView.prototype).originalAttachNative = (<any>ScrollView.prototype).attachNative;
(<any>ScrollView.prototype).attachNative = function () {
    this.originalAttachNative();
    const newDelegate = MyUIScrollViewDelegateImpl.initWithOriginalDelegate(this._delegate);
    this._delegate = newDelegate;
    this.nativeViewProtected.delegate = newDelegate;
};
